The invention relates to a cooling devimi for cooling the lubricant and also the cooling liquid of a motor.

The invention has as one of its principal objects the provision of means for accomplishing the above objects, which means 18 particularly adapted for association with a vehicle conveyance or railway car employing a cooling medium for'the motor.

A further object of the invention is the provision of a heat exchange device arranged in the circulating system of the cooling medium of the engine and the combination I therewith of a heat exchange device for the lubricant of the motor, the heat exchange devices being arranged to accomplish circulation of the lubricant and cooling medium and to subject both the lubricant and cooling medium to an air current to thus efliciently 0 dissipate the heat of both'the lubricant and the cooling medium and cause it to be returned to the motor in a cooled condition.

A further object of the invention is the provision of means for forcing air through heat'exchange devices and to arrange said heat exchange devices and said means within a chamber to thereby cause circulation of air through theheat exchange devices.

The invention also has as anobject combining and arranging the various elements entering into the structure so that a simple and efiicient construction is produced.

The invention will be explained and more readily understood when read in conjunction with the accompanying drawings which illustrate various embodiments of which the invention is susceptible, it being therefore obvious'that other changes and modifications may be resorted to Without departing from 19 the spirit of the appended claims forming a part hereof. p

Figs. 10 and 11 are respectively side and plan views of a modified structure which may be utilized to accomplish features of the invention; and

Fig. 12 is another modification.

The invention is illustrated as associated with a street or railway car generally designated 10 which employs an internal combustion engine generally designated 11 as the motive power for the car. The device whereby the lubricant and the cooling medium for the motor 11 is cooled is generally designated 12 and is, in the adaptation thereof shown in Fig. 1, applied to the roof of the vehicle or car 10. The water jacket of the motor 11v has one end of a pipe line or extension 13 attached to it, the opposite end of the pipe 13bein connected with a tank'l l, the latter of whic in turn, is connected with the upper end of an inclined radiator or heat exchange device 15 to which a return pipe 16 is connected, the opposite end of the'pipe being attached to the water jacket of the motor 11. From this it will be seen that as the cooling medium or water contained in the jacketof the engine 11 becomes heated, it will rise, flow through the pipe 13, be discharged into the tank 14, grfttvitate through the heat ex- 6 is a section taken on line" 6-6 of change device'o'rradiator 15 and be returned through ,the medium of the ipe 16 to the water jacket of the engine, t us producing I during circulation. A pipeconnection 1 is provided which may have onejend thereof connected with the oilsump or-soine' other suitable portion of the oiling or lubricating system of the engine 11. This pipe17 has the opposite end thereof, such as 18, connected with the pipe connections generally designated 19 which feed the heated-oil rising in the pipe 17 to the heat exchange devices respectively designated 20, 21, 22 and 23 (see Fig. 2). Pipe connections 24 are formed between these heat exchange devices ust referred to and a pipe connection 25. This pipe connection 25 extends from the connections 24 and has its opposite end attached with the engine 11 and completes a system for conveying oil from the engine 11 to and through the heat exchange devices and back to the engine. From this it can be seen that a means is provided for cooling both the cooling medium for the engine and the lubricant therefor.

The invention contemplates the provision and utilization of a means for producing air currents, forcing and directing these air currents through the radiators above referred to, to thereby facilitate cooling of the'cooling medium for the engine and the lubricant therefor. This means includes power operated or air current inducing fans respectively designated 26 and 27 which are de signed to be driven by a motor 28, preferably electric, and are arranged or located between the heat exchange devices generally designated 20, 21, 22 and 23 and the heat exchange device generally designated 15. These fans and heat exchange devices are arranged with respect to each other so that a current of air induced by the fans is caused to travel through the radiator or heat exchange devices 15, 20 to 23 and be discharged from a casing generally designated 29 in which the motor 28 and said fans are housed. The motor 28 is mounted upon a standard 30 which holds the motor with respect to other portions of the structure,

Byreferring to Fig. 2 it will be seen that the heat exchange device generally designated 15 is composed of a plurality of separate heat exchange devices 31 and by referring to Fig. 5, the manner of mounting these separate heat exchange devices will be seen. As illustrated in Fig. 5, it will be noted that the tank 14 has a longitudinally arranged and laterally extending tubular part 32 and that the lower wall of this tubular portion 32 is provided with one or more apertures such as 33 through which communication is afforded with the interior of the tank 14.

Each of the heat exchange devices 31 have their opposite ends respectively provided with headers 34 and 35 which are connected with each other through the agency of thetubes 36 which provide water passages. These water passages are elongated in cross section andhave the cooling fins 37 arranged transversely thereof. The header 34-which is adapted to be connected with the tank 14 is provided with one or more apertures 38, the apertures being designed to communicate with apertures such as 33 provided in the tubular extensions 32 of the tank 14, A gasket 39 is arranged between the tubular extension 32 and the header 34 and said header and tank 14 are held in associated relation with each other through the agency of bolts such as 40 which extend through the tubular extension 32, the apertures 33 and 38 into connection with a spider 41, the spider being provided with an internally threaded collar 42 for the reception of the threaded end of the bolt 40. It is manifest that this provides a means whereby the tank 14 and the adjacent end of the heat exchange devices such as 31 are connected and held in associated relation with each other, the con-. nection permitting circulation of water from the tank 14 through the apertures 33 and 38 into the header 34, from which the water gravitates through the tubular ducts 36 into the header 35 and thence through the pipe.

connection 43, it being understood thateach of the heat exchange devices 31 are provided with a pipe connection such as 43 and that these pipe connections 43 are, in turn, connected with the return pipe 16 which, as before stated, connects with the water acket of the motor. The headers 35 of each of the heat exchange devices 31 are supported through the agency of brackets respectively designated 44 and 45, the bracket 44 being connected with an angle iron base or support 46 which may be secured to the roof of the conveyance. This angle iron support 46 also provides a means to which the end wall 47 may be attached. The end wall together with the side walls 48 and 49 provide a compartment or housing for the several heat exchange devices 31 it being understood that i the bracket is connected with the end wall 47 and thus with the bracket 44 provides a means for supporting the adjacent ends of the respective heat exchange devices.

The side plates 48 and 49 and the end plate 47 are secured to a frame including the angle iron elements 50, 51, 52 and 53 which are connected at their forward ends to the-transverse-1y arranged angle iron members 54 and 46. The side walls48 and 49 are provided with the outwardly extending flanges 55 and 56 which are, in turn, bolted to the vertically arranged standards or supports respectively designated 57 and 58. These standards or supports 57 and 58 also support the tank 14. The housing 29 for the motor 28 is and the fans 26 and 27 are connected with the standards '57 and 58. The radiators or heat exchange devices 20, 21, 22 and 23 form ends for the housing, the heat exchange devices being separated from each other to provide spaces 61 and 62 through which airmay travel relatively to the housing. These heat exchange devices 20 to 23 include headers 63 and 64 located adjacent the opposite ends of the heat exchange devices and each of these headers has apipe connection 65 and a pipe connection 66 extending therefrom, the

aeoaera former bein connected with the lubricant conduit 18, t e pipe connections 66 being connected with the return pipe 24 and the passage 25 to return the cooled lubricant to the engine after it is-passed through the heat exchange devices 20 te 23. These heat exchange devices substantially correspond in construction with the heat exchange devices 31 and thus include a plurality of-tubular passages 67 and transversely arranged fins 68, the opposite ends of the tubes 67 being respectively connected with relativel thin plates 69 and 70'which respectively orm closures for the headers 63 and 64. These plates 69 and 70 and also the corresponding plates of the heat-exchange devices 31 are provided with longitudinally extending flanges 71 which are inserted in grooves-72 formed in the parts63 and 64 providing the headers, are brazed or otherwise secured to these portions and permit linear extension of the tubes without causing a break or leak between the plates such as 70 and the header with which they are connected.' v

The headers 63 and 64: are respectively provided. with an'angle iron bracket 73 and 74, the bracket 73 being attached to an angle iron frame memoer 75 which extends from the angle iron uprights 76 to the supports 57 and 58. The lower ends of the heat exchange devices 20 to 23 are supported through the tioned parts being held in associatedrelation through the agency of any suitable means such as the bolts 79.

The fans 26 and 27 are-arranged to rotate in a. housing formed by the top'wall 59, the side wall (see Fig. 7) the roof of the vehicle and a wall such as 80, it being understood that each end of the housing generally designated- 29 is provided with a well such as-80. These walls aresupported at their innermost ends by an annular reenforcing band 81 which connects these walls and the wall such as 60. From this it can be seen that upon rotation. of the fans air is drawn through the open side 'sired to cool.

rents entering the housing and insure their passing through the heat exchange device generally designated 15 before they enter the tan housing. 1

The modified structure shown'in Figs. 10

and 11 contemplates the utilization of a motor 83, fans 84 and 85 which are driven by the motor, heat exchange devices 86 and transversely arranged heat exchange devices 87, 88, 89 and 90. The heat exchange devices 86 are connected with a tank 91 and are each provided with an outlet pipe connection 92 in a manner and for a purpose similar to that described in connection with the structure shown in Fig. 1. The structure-shown in Figs. 10 and 11 difiers from the structure shown in Fig. 1 in that the heat exchange de-' vices 86 are arranged relatively to a casing 93 to form a closure for an open side of the casing, the heat exchange devices 87 to 90 b- I ing disposed relatively to the heat exchange devices 86 to provide part of a side wall of the casin 93, the casing being completed through t e agency of plates such as 94 and 95 and an end plate 96, it being'unde'rstood that the opposite sides of the casing 93 are provided with plates such as 94 and 95 to vcomplete the housing. The heat exchange devices 87 to90 are each provided with an inlet 97 and an outlet 98to thus permit a circuit to be completed between-these devices and the engine, the lubricant of which it is de- The side plates 94 and 95 arranged on opposite sides of the housing and the end late 96 are held in associated relation by .lieing connected with a supporting frame 99 therefor which, as clearly shown 1n- Fig. 10, is connected to uprights or supports 100 such as those previously described in connection with the structure illustrated in Fig. 1.

A water inlet 101 is connected with the of the casing 12, the heat exchange devices gank 91, the outlet being designated at 102,

generally designated 15, through said devices into the housing generally designated 29- in which the fans are located, and thence caused to flow through the opposite ends of this last mentioned housing and through the heat exchange devicesrespectively designated 20 :to 23 which will subject the cooling fluid for the engine and also the oil or lubricanttherefor to the cooling effect of the air cur rents produced by the fans. It is evident that as the water and lubricant of the motor become heated itrises, flows through the respective heat exchange devices and /is returned in a cooled condition to the motor.

7 An arrangement such as this permits the en-- and cool the cooling medium for the engine and the lubricant therefor. The structure illustrated in Fig. 12 di'scloses another arrangement which may be employed. This structure contemplates the use of a casing 105, fans 106 and a heat exchange device 107. In the structure the side walls of the casing 105 are extended beyond the heat exchange device 107 and provide supports for the vanes 108 which extend transversely across the heat exchange device 107 and provide means for protecting and directing air toward this heat exchange device arranged within the casing. It is manifest that depending upon the direction of rotation of the fans, that air may be drawn through either set of heat exchange devices into the fan housing and be expelled therefrom. It is also evident that the structure forms an efficient arrangement which will quickly and effectively cool both the lubricant for the engine and the cooling'medium and accomplish cooling of relatively large quantities of these commodities.

It is understood that the structure of the heat exchange devices shown in Figs. 10 and 11 corresponds with the structure of these same devices employed in the previously described structure, in that the structure connected with the tubular elements permits the tubular elements to expand and contract without causing breakage and leakage.
